8 Claims. (Cl. 189-75) This invention relates to a window framestructure and particularly to improvements in the jamb assembly thereof.

The invention is embodied in a window assembly of the storm sash screentype wherein three guide channels are provided adapted to carry threeslidable sash. Two of these sash may be'storm sash and thethird sash ascreen sash. The invention is here shownas embodied in such an assemblyformed of metal such as aluminum.

An object is to provide such a window structure wherein the window sashmay be readily removed from the inside of a building for washing andeasily and quickly replaced in position.

A meritorious feature is the provision of a jamb assembly so constructedthat the removal and replacement of sash is facilitated by partiallydisassembling the jamb structure and this can be readily and quicklyaccomplished.'

Another meritorious feature is the provision of a jamb assembly of thecharacter specified wherein the lower portion of certain guide channelmembers may be detached from the remainder of the jamb assembly so as tofacilitate the removal of sash therefrom.

A further meritorious feature is the provision of a jamb assembly of thecharacter described wherein two of the guide channels are embodied inparts which are so associated with the remainder of the assembly as todene with such remainder three guide channels but the parts which makeup the two guide channels may be removed from the remainder of theassembly so far as the lower portion of the assembly is concerned whileremaining a part thereof through the upper portion of the assembly.

Another object is the provision of a jamb assembly in a window structureof the character specified wherein one of the guide channel walls isbent at the upper corner of the lower portion of such guide channel outof the plane of the channel and into the plane of the adjacent channelforming a yielding part which is adapted to engage underneath a sashwhen elevated thereabove to support the same.-

Other objects, advantages and meritorious features will appear from thefollowing description, claims and accompanying drawings, wherein:

Fig. 8 is a horizontal sectional view taken on the line 8-8 of Fig. 1;

Fig. 9. is a horizontal sectional view taken on the same line as Fig. 8but showing the lower portions of two of the guide channels withdrawnfrom the remaining portion of the assembly;

Fig. l0 is a horizontal sectional view taken on the line 10-10 of Fig.l.

The window structure is shown as mounted within a window opening on theoutside thereof. Such window opening is provided in a building that isordinarily constructedwith a stationary jamb element 20 which israbbeted asat 22 providing a shoulder upon which the assembly may besecured by means of screws, nails or the like 24, as shown particularlyin Figs. 3, 4, 6 and 7. The window opening of course is provided with aheader and a sill shown in dotted outline in Fig. 1.

My window structure comprisesa pair of opposedy of sheet metal shaped soas to delne three header wells within which the upper rails of the threesash carried by the window structure may be received. The two jambassemblies -are connected together at the bottom by a sill assembly 28,shown more particularly in Fig.`2 which exhibits an upstanding portion30 terminating in a ange 32 adapted to seatupon the stationary windowsill. The portion30 is provided with an upstanding ledge 34 on theinside of the window opening. The invention claimed resides particularlyin the construction of the jamb assemblies. The two jamb assemblies aresimilar.

Each jamb assembly comprises a base channel member 36 which is directlysecured by the screws 24 to the stationary jamb on the window. This basechannel member extends through the length of the jamb assembly.Connected with and seating kupon the base channel memberk The screws 24extend through the leg 40 of the Z-shaped member and secure the samewithin the base channel, as shown particularly in Figs. 3 and 4. Theother leg of the Z-shaped member which is indicated as 42 and whichprojects in the opposite direction from the leg 40 constitutes a sidewall of one of the three guide channels. This leg 42 may be folded overupon itself as at 43 as shown in Fig. 4.

There is a guide channel sub-assembly which is made up of two guidechannel members. One guide channel member is indicated by the numeral44. It is twice the width of a guide channel runway. It is seated uponthe base of the Z-shaped member 38. It has one side wall 46 which isspaced such a distance from the side wall 42 of the Z -shaped memberthat it defines therewith one of the three guide channels. The otherguide channel member which goes to make up the guide channel subassemblyis indicated by the numeral 48. It is seated within the guide channel 44as shown particularly in Figs. 3 and 4. It has a guide channel wall 50which is so spaced from the guide channel wall 46 that it definestherewith a guide channel. It has another guide channel wall 52 whichwith the wall 50 defines a guide channel.

The guide channel wall 52 is bent over upon itself as at These jambassemblies are secured to-A frictionally received within the channel ofthe leg 40 of the Z-shaped member, as shown particularly in Figs. 3, 4,6, 8, 9 and 10. The engagement of the lip portion of the folded overwall 54 within the channel of the leg 40 of the Z-'shaped member 38 iswhat holds the sub-assembly upon the Z-shaped member.

Throughout Ythe upper portion of the jamb assembly the screws 24 extendalso through the leg 54 and serve to retain the parts together.Throughout the lower portions of the assembly the screws do not extendthrough the lip ofthe wall '54 and such lower portions of thesub-assembly are therefore readily removable, as shown in Fig. 7.

It will be seen that the sub-assembly which is made up of the guidechannel 44 and the guide channel '48 is divided into upper and lowerportions, as shown particularly'in Figs. 6 and 7. The upper portionshave a vertical dimension greater than the vertical dimension of thesash 'that are slidably mounted within the window assembly. The sash maytherefore be elevated into the upper portion of the sub-assemblyentirely clear of the lower portion and permitting removal, as shown inFig. 7 by withdrawal of the lip 54 from the channel of the Z-shapedmember.

In the window assembly the upper storm sash is indicated as U, the lowerstorm sash as L, and the screen as S. These sash structures are shown inposition in Figs. l and 2 with the screen and one of the sash lowered inFig. 2. In Fig. all three sash are shown as elevated above the lowerguide channel assembly and into the upper guide channel assembly. Whenit is desired to remove the sash from the assembly they are raised intothe upper portions, as shown in Fig. 5. The lower portions of the guidechannels which make up the sub-assembly may then be withdrawn, as shownin Fig. 7 because the lip S4 in the lower portion of the sub-assembly isof less width than the lip in the upper portion and is not pierced bythe screws 24.

The side wall 46 of the channel 44 has its upper cornerbent out of theplane of the channel, as shown at 58, in Figs. 5, 6 and 7 so that suchyielding corner bend is disposed within the outer guide channel andtherefore will serve to hold the sash U in the elevated position whenthe sash is raised thereabove, as shown in Fig. 5. Also as .shown inFig. 5, the side walls of the channels preferably present a wave-likecontour as shown by reference character 60 so that friction is exertedupon the sash sliding through the channels sufficient to maintain themin positions of elevated adjustment.

It is apparent, therefore, that in a window frame as herein describednot only will the sash be maintained at adjusted elevated positions butthe sash may be relatively easily removed from the frame. Such sash maybe raised into -the upper portion of the window frame. The subassemblyof each janib assembly may then be withdrawn as shown in Fig. 7. Eachsub-assembly may be withdrawn inwardly. Upon withdrawal of thissub-assembly a sash may be lowered from the upper half of the frame intothe'lower half. Such sash may then be moved laterally from the frame.Each of the sash may be thus removed.

For replacement the sash may be inserted into the lower 'half of theframe and elevated. Upon elevation of the sash the opposed assembliesmay be reinserted and the window is ready for use. It does not requireany tools or removal of screws or the like to effect the removal andreplacement of the sash.
